Analysis
Of Existing Solid Waste Management Situation In Dhaka City

Based on
secondary data collected from different sources, required dumping area for solid
waste in Dhaka city was calculated for the next 10 years, which is 1109.5 acres.
At the same time by using empirical formula, the quantity of rapidly
decomposable gas was calculated to be 13.9 ft3/lb, slowly
decomposable gas 16.7 ft3/lb and development of leachate was
calculated as 1.70 ´ 106
gal per 10 years. It has been found that due lack of landfill regulation the
solid wastes are indiscriminately disposed around the city. Due to this
indiscriminate disposal of solid waste, the gas and leachate are emitted to the
natural environment, which is creating potential environmental impacts. The
potential impacts are ozone depletion, toxic VOCs in air, odor, noise, birds,
rodents, insects etc., litter dust, explosion and fire hazards, vegetable
damage, soil pollution, surface water pollution. A unique landfill regulation
and solid waste management policy is required to control the emission from the
solids. Otherwise it will create an environmental disaster in the future. |
